Y p EXTRACTOR FOR AUTOMOBILES. v

Application filed Mayl 6,

This invention relates to extraotors and more particularly to an extractor of'the windlass type by means of which a miredk automobile may be readily removed from a mudhole. y

One object of the invention is to provide an extractor of theV type specified which may be folded into a compact mass and readily transported from one place to another.

Anot-her object of the invention is to provide the extractory with a winding drum for a pullingv cable and guide rollers for'the cable which are rotated from the windingr r drum so that they may serve to feed the cable to the drum in addition to "guiding movement of the cable.

Another object ofthe invention is to provide theextractor with a brace rod by means of which it may be retained in an uprightposit-ion when in use.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing the improved extractor in side elevation;

Fig. 2 is a top plan view of the extract-or when folded;

Fig. 3 is a view showing the extractor in end elevation.

The extractor forming thesubject-matt'er of this inventionis provided with a frame which is of a rectangular formation and formed in sections, indicated in general by the numerals 1 and 2. The upper and lower bars 3 and 4 are firmly secured to vertically disposed end bars 5 and bracing blocks 6 are disposed at the intersection of the end bars and upper and lower bars so that these lbars will be braced and a strong frame thereby provided. At their inner or meet-ing ends the upper and lower bars of the frame sections are joined by hinges 7 so that the sections may be extended to an operative position, asrshown in Figs. 1' and 3, or folded to the collapsed position shown in Fig. 2. It should also 'be noted that thev upper and lower bars of kone section carry hasps 8 which are adapted 'tol be lengaged, with the staples or other equivalent' keepers 9,car ried by t-he companion bars of' the other V:trame section and' -securely but releasably hold .the .sections .in the: extended operative position when wedges or other suitablefas- 1926.

teners are passed through the keepers. A recess 10 is formed in the inner end of each upper and lower bar, and these recesses are lined by metal strips 11 which extend across the end faces of the bars atopposite sides of the recesses. rIhe recesses of the companion bars register when the frame sections are in the extended position and'form bearings.

The drum 12 upon which the cable 13 is to be wound extends between the upper and lower bars of the frame and is provided with a spur 14 with which an intermediate portion of the cable may be engaged. The cable may thus have its intermediate portion wound upon the drum and its end portions extended from the drum in opposite directions and passed through openings formed in the end bars 5 of theframe. The

upper and lower portions of the drum 12 are journaled in thev bearings formed byL the companion recesses 10 of the bars 3 and 4 and the portion of the drum which is :rotat-` ably mounted in the upper bearing is extended upwardly above the frame to provide a post lwhich terminates at its upper end in spaced arms 16. Acrosshead 17 is secured between the arms 16 by rivetsor other suitable fasteners 18, and this crosshead extends from opposite sides of the post and is open at its ends in order to receive handle bars 19, by means of which the drum is to be rotated. These handle bars may be of any desired length and' since they may be re` -moved from the crosshead 17 they will not be in the way when the frame is folded.

The drum is formed with an axially extending passage adapted to receive a bracing rod 20 which is formed of strong metal and of such length that its `upper and lower ends will project from the upper and lower ends ofthe drum, as shown in Figs. 1 and 3. The lower end of the rod 20is tapered to form a penetrating kpoint which may beheld in engagement with the ground by one of the operators ofthe extractor so that the frame will be retained in a vertical position. The .rod will, `of course, be moved along the ground from one place to another as the cable is wound upon the drum.

In order toguide movement ofthe cable into and out of the frame each of the end bars 5. has vbeen provided with guide rollers Cil 2l and 22. The rollers are provided With shafts 23 and :2li which are rotatably mounted by bearing brackets 25 and 2G, and byreterring to Fig. 3 it Will ybe seen that the shaft lprojects from one side ot' its 1roller 2l and carries a pinion 27 Which meshes with a pinion 28 at the lower end of a shaft 29.` A shaft 29 is, of course, located at each end of the trame, and these shafts are .rotatably mounted in bearing brackets 30 carried by the end portions of the Itrame. The shafts 29 project upwardly above the frame and at ,their upper ends are provided With Worms 3 1 which mesh `With Worm gears 3.2 at `the outer ends of shafts 433 Which entend longitudinally -oit the upper bars ,3 ot the ltrame sections land are rotatably mounted in bearings 34. llhese shafts 33 carry beveled gears or ipinions 3,5 at their inner ends which bare :adapted to mesh with the `beveled teeth ofthe gear plate or disk 36 secured rigidly vupon the post 1:5 ot the drum. From an inspection of Fig. l, it Will be readily seen that, when the drum is rotated by ymeans oit the handles 1,9, rotary motion will be transmitted from the Vdrum to the rollers 2l and since the cable extends between `vthe rollers 2l and 22 it will be `easily fed into and out Iof vthe frame by the rollers 2l as Well as being guided in its movement. The .gears andv pinions must, .of course, (be so proportioned that the rollers 2l Will eed the .cable at the proper rate of rspeed in comparison to the speed at which the ,cable is Wound onto or oli the drum. Belowv the gear disk 36 lthe post carries a ratchet Wheel ,37 adapted to `be engaged by a parvl so that rotation oi .the drum to unwind .the cable may be .prevented. The pawl may, otcourse, 'be moved out ot engagement with the ratchet Wheel `so that the cable may be unnound from the drum .when necessary.

When this dev-.ice is in use, .011@ @ad .01 the .Cable is Seemed t@ a tra@ .01 Stake driven into a roadway and the .other end of the .cable is attac-lied to the aide of the automobile vlill .iS .to 'be @Xtracted- The drum ist-.116.11 rotated through the medium of the handle bars and as the drum is rotated the cable is Wound upon the drum. A, pulling action will, therefore7 be exerted which will cause the automobile te be extracted trol-n the raudhole in which itlias become mired. After the automobile has been entracted from the -m-'ndholeJ the cable Will be released ,i1-toni thenaxle and stake or other permanent sup-y port to `which it has been attached the hasps 8 .may be released from the keepers 19 so that the traine may be folded into a compact mass. The rod 20 will' not, of ceurseybe Idriven firmly into the ground as it must be moved along theV ground as the cable is Wound upon the druni.
